Radar is a radio device that uses radio waves to determine the location of objects. To avoid interference from surrounding buildings, radar towers are typically as high as 100 meters.
About 1 meter, due to the requirements of radar performance, the fundamental frequency of the radar tower must not be less than 1.0 Hz. Through a large number of calculations and analyses, some conclusions have been drawn that can significantly improve...
The regularity of the basic frequency of high radar towers. Radar towers are widely used in modern applications, whether at sea or on land, in traffic, and for navigation.
Position, velocity measurement, search, etc. Meanwhile, the seismic response of the radar tower was analyzed using the response spectrum method, time history analysis, and random vibration method. Calculations
The results indicate that the radar tower meets the seismic code requirements for inter-story displacement.
Tower Structure:
The entire steel tower is mainly composed of three major parts: the tower head, the tower body, and the tower legs. For guyed towers, the guyed section is also added. The tower head extends upwards from the tower legs to the tower frame section.
Sharp changes (represented by lines) above the portion mentioned are the tower head. If there is no abrupt change in cross-section, the part above the lower horizontal brace is considered the tower head. Tower leg
Above the base, the section of the tower frame is called the tower leg, the tower body, and the part between the tower leg and the tower frame is called the tower body.
